Serialization of 'Closure' is not allowed #902

Open snez opened 1 year ago

snez commented 1 year ago

We have started noticing failures in our test suite about a week ago, with no changes on our side. After investigation, we found the problem to have been caused by the release of v4.3.0 of the Magento functional testing framework. After downgrading to v4.2.1, the problem was resolved. Reporting the details here for reference.

Preconditions

  1. Magento 2.4.6
  2. PHP 8.2
  3. v4.3.0 of the framework

Steps to reproduce

  1. Implement an MFTF test which fails intentionally. Successful tests do not have this problem
  2. Add the test in a test suite, with at least one more test after it

Expected result

  1. The test should fail with a recorded screenshot
  2. The next test should start

Actual result

  1. The test fails, and the entire test suite stops in its track, preventing allure reports from being generated. Example below:

  [waitForFullScreenIframe] wait for element "//iframe[@name='acsFrame']",30
  [saveScreenshot] save screenshot
  [] [START AFTER HOOK]
[] [logoutStorefront] StorefrontCustomerLogoutActionGroup
  [storefrontSignOut] am on page "customer/account/logout/"
  [waitForSignOut] wait for page load 60
[END AFTER HOOK]
 ERROR
